displays the classic Bland-Altman difference plot with limits of agreement, prints the mean difference and both agreement limits (along with 95% CIs) and returns a list of relevant parameters (the mean difference, its SD and SE, upper and lower agreement limits, their SE, and the t value used in the calculation of CIs)
